SOURCE: I have a coolant leak

Sounds like either the water pump or the thermostat housing. The water pump has a small hole in the bottom where the shaft comes through, when the water pump gets worn it will leak here so you know to replace the pump. The thermostat housing will be at the motor end of the upper radiator hose where it attaches to the motor. Hope this helps.

SOURCE: hole in radiator

Depends On The Size On The Hole And How Much You Have To Spend Also By The Location Of The Hole. If Its A Tiny Hole You Can Use Jb weld Purchasable At Most Auto Parts Store. If Its A Small Crack They Sell An Additive That Will Seal It At Any Auto parts Store.
If Its A Bigger Crack Or Hole You'll Need To Find Someone To Weld It For You.

For The jb Weld And Additive It May Not Last But In Some Instances Lasts A Really Long Time.

Usually once a radaitor starts leaking you should replace it since it is a pressurized system and could cause overheating.

SOURCE: water leak inside the car

Whats causing this is that the drain hose for the evaporator is clogged and overflowing into the car. what has to be done is get under the car and find the drain hose, which is going to be on the passengers side of the car by the firewall, and get either compressed air and blow into the hose to try to free the blockage

Will an air pocket in the coolant system cause it to overheat or over pressurize on a 2001 Nissan Sentra ?


1. The radiator cap if working correctly it will release pressure in the system provided the cap you have is the correct pressure setting. If you are having a problem with pressure then replace the cap with a new radiator cap with the correct pressure setting. Do not use a cap with a pressure setting other than the original equipment pressure spec. So you do not go to the parts store and buy any radiator cap on the shelf that fits because they come with different pressure ratings and some of these will be totally unsuitable for your car.

2. If the pressure valve is stuck in the "old" cap the pressure release system will not work.

3. Overheating
Air pockets in the cooling system can definitely cause overheating and can retard coolant flow through the system. If you are draining the radiator to replace the coolant or replacing the radiator you need to follow the correct procedures for bleeding air out of the system for that particular engine after coolant refilling. Some engines have bleeder screws on the cooling system to assist in the air bleeding procedure and some don't.

There are various causes for overheating so don't assume it will necessarily be solved by bleeding any remaining air from the cooling system and replacing the radiator cap with one that works.

Other causes can be...........
1. Faulty cooling system thermostat. (Replace the Thermostat)
2. Faulty water pump, especially if the impellers have corroded away or have disintegrated in the case of those design genius water pumps with plastic impellers. (Replace the water pump)

3. Cooling fans not working and if so the cause needs to be tracked. Check that your fans are kicking in. If the engine is overheating the fans should be running because they will switch on when the coolant reaches a specific temp and well before the coolant gets excessively hot.

4. A partial blockage in the coolant passages inside the engine but not in the radiator if you have a new one. If the coolant is not changed at the required intervals(frequently the case with many owners) or is over diluted with water you can get a build up of debris. If products like stop leak have been used in the system this can create similar problems with partial blockages inside the engine coolant passages.

5. A compression leak into the cooling system.
If you have bled air from the system and have continuous air bubbles in the cooling system I would suspect a compression leak. In that event a basic leak down test will show if you have compression gasses leaking into the cooling system and from which cylinder(s). The spark plug is removed and compressed air is forced into the cylinder via the spark plug fitting and air bubbles will show up in the coolant of there is a leak into the cooling system.
--------------------------------
Have the problem with overheating addressed immediately. Running the engine with an overheat condition will cause expensive engine damage many times the cost of fixing the overheating issue.

Coolant leak


Pull your oil dipstick and look at the level and appearance of what's on the stick.

If the oil level is WAY high, and it looks like chocolate milk, that's where your coolant is going.

It means either the head gasket is blown, or the cylinder head, or the engine block is cracked.

The fan running is normal. you need to find where the coolant is leaking. If there are no visable leaks. then suspect the radiator/reservoir cap.

How to replace coolant for nissan altima 2006


Park the Nissan Altima on a flat surface and set the parking brake. Next, open the hood and check the external temperature of the radiator. If the radiator is warm to the touch, wait for the radiator to cool before you continue.

Twist the radiator cap one turn to relieve any pressure. Step back from the radiator and allow a few seconds to pass, and then completely remove the radiator cap.

Place a bucket or tray with at least a 2-gallon capacity underneath the radiator and below the drain plug. The drain plug on a Nissan Altima is on the passenger side bottom of the radiator.

Loosen the drain plug and let the old coolant drain completely into the bucket. Take care while loosening the drain plug, because it's plastic and can be brittle. Pour the old coolant into a sealable container for proper disposal later and put the bucket back under the drain plug opening.

Close the drain plug and pour distilled water into the radiator until it's full. Then, open the drain plug and let the water flow into the bucket. Keep repeating this procedure until the water runs clear and debris free into the bucket. You will need at least 3 gallons of distilled water.

Make sure to tighten the drain plug and fill the radiator with fresh coolant. Refill the radiator to within an inch of it overflowing. Check the drain plug and hoses for any possible leaks.

Start the Nissan Altima and turn the heater to the high setting. Let it run for about 10 minutes and shut the engine off. Check the coolant level and refill, if necessary. Finally, put the radiator cap on and close the hood.

Leaking anti freeze and metal scraping sound coming from front passenger side of car. just replaced radiator 4 months ago. no white smoke out of tailpipe


It sounds like you need a water pump. When the bushing in the water pump shaft wears out it makes a horrible grinding marbles together kind of sound and coolant leaks past the shaft seal.

After it rains water is in trunk Nissan Altima


When diagnosing a water leak, here's a handy tip. Check the accumulated water. If the water is dirty, look for leaks from the underside of the vehicle (floor, wheelwells, etc). If the accumulated water is clean, look for leaks from the topside of the vehicle (trunk seal, window seal, etc). To find where the water is coming from, shut yourself in the trunk with a flashlight and have an assistant run water over the trunk with a garden hose. You may have to remove some of the interior trunk trim to see exactly were the water is coming from, but chances are you'll find it. Also another common cause of water leaks are from impact damage, so check for collision damage repair. while your in there. -hope this helps.

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.
